Stiebel Eltron Mini-Tank Series Water HeatersVery economical. Excellent choice where only 110/120v power is available and water is used infrequently. Space saving design - conveniently mounts under a sink or in a nearby cupboard. Available in 2.5 and 4 gallon tank storage capacities.

Stiebel Eltron DHC Series Tankless Water HeatersEconomically-priced point-of-use tankless water heaters up to 10KW suitable for almost all point of use water heating applications. 110/120 volt and 208/240 volt models available. Best suited to single applications with a relatively consistent water flow rate and pressure.

Stiebel Eltron DHC-E Series Tankless Water HeatersTrue thermostatically-controlled tankless water heater with full flow-based power modulation. Available in power range up to 10 KW (208/240 volt configuration). Excellent choice for point-of-use applications where flow rates or water pressure may vary due to multiple water demands or well pump pressure changes or where very low activation flow rates are required. Features digital temperature selector.

Stiebel Eltron Tempra Series Tankless Water HeatersUsed mainly for whole house applications, these thermostatically-controlled tankless water heaters feature full flow-based power modulation and can be used for more demanding point-of-use applications where higher flow rates are required. Available in power capacities from 12 to 36 KW. Excellent choice for demanding point-of-use applications where flow rates or water pressure may vary due to multiple water demands or well pump pressure changes. Features digital temperature selector.

Point of Use Tankless Water Heater Selection Guide

The most important considerations when selecting a point-of-use tankless water heater are:

Water Flow Rate

Incoming Water temperature

Activation Flow Rate

The chart below will give you some guidelines as to the flow rates of common water demands. It is important to note that the flow rates of these applications will vary due to water pressure and other factors. Accordingly, you are encouraged to test you actual flow rate of your application for a more precise model determination.

Application

Flow Rate inGPM at 60 PSI

Bathroom Vanity Sink Faucet

0.5 to 1.5 GPM

Kitchen Sink Faucet

1.0 to 2.2 GPM

Typical Shower

1.5 to 2.0 GPM (Max. 2.5 GPM)

Typical Bath Tub Faucet

2.0 to 3.0 GPM

Clothes Washer

1.5 to 3.0 GPM

Once you have determined the flow rate your require, use the map and chart below to determine which models are able to meet your flow rate needs based on your incoming water temperature. It is important to verify that the activation flow rate for the model selected is less than the flow rate of your application or the heater will not activate.
